Re: Can't add freon to 2002 ford explorer air conditioner
Try hosing down the condenser with water from a hose, makes the freon condense more. On the other hand, are u sure it needs more freon and there isnt another problem?

You have to add 134a refrigerant while the engine is running and the A/C is on max with temp setting at lowest level. Without the proper charge in PSI, the compressor will not kick on. If the pressure is correct under those circumstances, You either have air in the system ( take it and have it pumped down then refilled) or the compressor is bad.
Take to a shop that has the proper gauges and ability to vacuum the system properly. Do not simply try and add Freon as it only causes an air gap and false readings. In addition, some cars require a resetting of values on the cars computer brain in order to function properly.
Please explain. You can't add freon ? The freon won't stay in the system ? You know the engine and the compressor has to be running to add freon, right ?
If the system is blowing hot. Then u need to take to a shop so it can be checked for leaks. Also the system will need to be vaced down by a machine to get all the air out of the system and moisure. Then freon can be added.
Adding freon to a car requires connecting the low-side service valve first, followed by the high side, recovering the existing freon, evacuating the system of air and recharging the system with new freon. You can use R-134a refrigerant for 1998 Ford Explorer. You can get all parts necessary for Ford Explorer at one place at http://www.carpartswarehouse.com/carparts/Ford/A-C_Condenser.html
FIRST I CHECK ALL FUSES AND RELAY.TO BLOWER MOTOR IF IT STOP BLOWING.AND CHECK FUSE TO HVAC SWITCH CONTROL.AND CHECK FUSE / RELAY TO AC COMPRESSOR.IF FUSE / RELAY GOOD POWER GETTING TO AC COMPRESOR CLUTCH COIL AND LOW PRESSURE SIDE 28 PSI AND HIGH SIDE 200 PSI. CLUTCH COIL IS OPEN.IF REFRIGERANT LEVEL LOW YOU MAY NEED MORE REFRIGERANT.YOU NEED AT LEAST 28 PSI ON LOW SIDE AND 200 - 220 PSI ON HIGH SIDE.IF ALL IS GOOD STILL NO AC PROBLEM COULD BE A FAULTY AC CLUTCH CYCLING PRESSURE SWITCH.
go to a parts store such as Advance Auto Parts or Auto Zone and buy the A/C recharging kit they have with the rubber line and connector that connects only on the side that you need to recharge your system. If you can put air in your tires you can out freon in your a/c system.
Yes you can add freon, the port will be on the line up at the accumlator tank (large silver tank on pass side close to the fire wall - will have a large black cap, does not look like a port) Get you a large can with a hose attached do not use it all save some for next year.
there is a port and it takes r123a and it has a green port on it but if it's leaked out you mave have to have it vachumed out, if you charge it be sure to get R134a with oil so that you don't burn up the pump, when the thing leaks it loses oil.
